House Dems urged to oppose Boehner's 'Plan B'

12/19/12 1:59 PM EST

House Democratic leaders are urging their members to unite against Speaker John Boehner’s “Plan B” to avoid the fiscal cliff.

Two tax votes in the House could comes as early as Thursday. The first would extend current tax rates for income $250,000 and below. The House Democrats’ whip operation is telling lawmakers to support that plan.

The second is the so-called “Plan B,” which would keep the rates for income up to $1 million. House Democratic leaders are calling for a “no” vote on that plan.

If House Democrats uniformly oppose the GOP proposal, Boehner (R-Ohio) would have little room for defections among his Republican conference. And his members are facing pressure from conservative groups such as Club for Growth and Heritage Action, who are also calling on lawmakers to oppose the plan.
